D.C Power Input
The power input connector accepts a DC voltage between +11.5 and +17V DC. When used
with a RED-BRICK 140 battery, the camera also receives battery status information. The power
input is protected against reverse-polarity connection, ESD, under voltage, and over current.

Note: It is very important that both of the +VBATT and –VBATT pins are wired
up. DO NOT fabricate any power cables with just one each of the +VBATT and
–VBATT pins wired up, as this can damage the camera power supply assembly.
Auxiliary Power Outputs
The camera provides two auxiliary power output connectors on its back panel. Each supplies
un-regulated +11.5 – +17V battery pass-through power. Maximum sustained current draw is 1
Amp per output. Outputs are over-current protected, and switched by camera firmware.
